摘要

The article suggests a method that allows to calculate the location of a crack in a rod using natural frequency. Cases of flexible and rigid fixing of left end of a rod are considered. The first case is simulated by mechanical system having two degrees of freedom and the second one - by the system with one degree of freedom. A crack is modeled by a spring.
